Title: Improvements in and relating to the treatment of hydrocarbon material and particularly to the cracking of such material
IPC: C10G45/00
Filed: 1931-10-27
Abstract: <PICT:0389871/III/1> In a process in which oils are cracked by direct contact with the products of the surface combustion of a permanent gas, e.g. the gases produced in the reaction, mixed with air, the body of porous and refractory material on which combustion is effected is arranged to form an extended radiant heating surface, and the inlet for the oils and the outlet for the cracked products in the cracking chamber are arranged so that the oil flows towards and the products are removed adjacent to the combustion surface.  Oils vaporized by passage through a heated coiled pipe 1 are led, after separation of non-volatile components and mixing with steam in a vessel 3, into a chamber 8 where they are cracked by contact with the gases formed by surface combustion of air and the gaseous products of the reaction burnt on refractory material 11 supported by a perforated plate 10.  The products pass through a pipe 13 to a chamber 14 packed with scrap iron where the cracking temperature is maintained.  The cracked vapours pass, preferably through a heat exchanger 22, to a dephlegmator 19 where heavy constituents are separated by contact with the crude oil introduced through pipes 25, 26, the oil being simultaneously topped.  The vapours pass to a bubble tower 30 from which uncondensed vapours are led through a pipe 31 to the usual condensers and storage while the condensate is led through a pipe 32 to a tank 33 and thence through a heat-exchanger 22 to the coil 1.  The proportion of air or oxygen used may be greater or less than that required to effect combustion of the permanent gas.

Plastic compositions containing albuminous matter.-An alkaline solution of. an albuminous substance, such as casein, blood, or intestinal mucus, to which phenol, creosol, &c. has been added is heated with aldehyde in the presence of ammonia, and the plastic mass is precipitated or separated by heating and moulded. Oils, such as wood oil, linseed oil, or turpentine, resins, varnishes, hydrocarbons, tricresyl phosphate, or mixtures of these may be added, and also fillers, such as fibrous substances, fabrics, wood-meal, kaolin, and pigments. Several examples are given of which the following are typical:-(a) 100 parts of casein are moistened with alcohol and dissolved in 500 parts of water containing alkali. 50 parts of creosol are added, the mixture is precipitated with an acid and the precipitate is freed from water. A further 50 parts of creosol, 10 parts of sodium hydroxide, and 50 parts of alcohol are then added. After the mass is dissolved, 20 parts of aqueous ammonia and 40 parts of paraformaldehyde are gradually added. The mass is heated and cast, or may be precipitated by an acid, dried, ground, and moulded under heat. (b) 100 parts of casein are dissolved with 50 parts of water and 10 parts of sodium hydroxide. 200 parts of cresol are added, water is evaporated, and the mass dissolved in alcohol. 20 parts of ammonia and 20 parts of paraformaldehyde are added, and the solution is heated until a resin is formed, whereupon it is filled into open or closed moulds, and allowed to harden. Another example describes the treatment of dried blood. The Specification as open to inspection under Sect. 91 (3) (a) comprises examples in which phenol, creosol &c. are not added to the casein &c. prior to the treatment with the aldehyde.

Title: Improvements in or relating to vehicle direction indicators
IPC: B60Q1/36
Filed: 1950-06-28
Abstract: 679,305. Road-traffic signals on vehicles. O'SHEI, W. E. June 27, 1951. [June 28, 1950] No. 16194/50. Class 118 (ii). A vehicle direction indicator of the semaphore arm type actuated by an electric solenoid to raise the arm from the non-displayed to' the displayed position is characterised by the provision of a return spring for the arm which commences to be loaded shortly after the initial movement of the solenoid armature in a direction to raise the arm. The solenoid armature can thus perform its initial movement, for example, to unlock the arm, unrestrained by the spring which, nevertheless, serves to assist the arm substantially throughout its return movement. The invention is described as applied to a direction indicator of the type disclosed in Specification 635,067 in which a solenoid 1 attracts an armature 2 to operate an indicator arm 3 pivoted at 6, the coupling comprising a spring-loaded lever 11 pivoted on the inner end of the indicator arm and carrying 'a roller 15 which co-operates with an L-shaped slot 10 in a plate 9 secured to the upper end of armature 2 and holds the arm resiliently locked when in its non- displayed position. A helical compression spring 20 is fitted within the bore of solenoid 1 and the lower end of the armature 2 is reduced in diameter to form a shoulder 21 which engages the spring 20 after the armature has moved sufficiently to release the lock by bringing the roller 15 opposite the horizontal portion of the L-shaped slot 10 (as in Fig. 2, not shown). The spring is of small gauge wire so that it compresses to a relatively short length and the shoulder 21 is formed at such a distance from the end of the armature 2 that the latter engages the bottom stop 22 and the spring is fully compressed when the arm is raised to the displayed position as in Fig. 3 (not shown). Specification 438,017 also is referred to.

Printing-surfaces.-To facilitate the assembling of printed and folded book sections into book form, one or more of the printing-plate clamping- devices of the printing-machine is provided with a printing-member adapted to mark the printed product at the line of fold, the position of the mark being different for each section. Fig. 9 shows a set of assembled book sections, the regular line of markings indicating a proper arrangement of the sections, and Fig. 1 shows a part of the printing-cylinder for printing the sections. The printing-plate 18 is clamped against a circumferential ring 17 on the printing-cylinder 15 by a series of clamps 19, and the printing-plate 20 is clamped between the clamps 19 and a second series of clamps 21. Each of the clamps 19 comprises a base 26, Fig. 3, slidably mounted in a groove in the cylinder and a head member 25 connected to the base by a screw 27. One of the screws 27 is provided with a type-high printing- lug 28, and a series of head members 34, 32, 30, Figs. 4, 5, and 6, are provided having printing- lugs 35, 33, 31 respectively at different distances from the screw 27. One book section is printed with one of the clamps provided with the screw 27 having the printing-lug 28 shown in Fig. 3. The screw 27 and head 25 are then removed and replaced by the printing-head 30, Fig. 6, and a second book section is printed. The heads 32, 34, Figs. 4 and 5, are substituted in succession for the head 30 and a book section printed after each substitution. The heads 30, 32, 34 may be secured to the base 26 with the printing-lug on either side of the screw 27 so that, for each clamp, seven different positions of the printing-lug is possible. Further, these printing-lugs may be applied to each clamp 19 in succession. If two different products are printed by the same set of printing-plates, two of the clamps 19 may be provided with the printing-lugs.
